参考链接：基于 Vue3 封装大华 RTSP 回放视频组件（PlayerControl.js 实现）_vue playercontrol大华的使用-CSDN博客

官方教程： WEB无插件开发包使用说明-浙江大华技术股份有限公司

碰到的问题： 1、PlayerControl.js默认是在根目录使用，如果不是在根目录使用需要修改对应文件中的的路径（我的前缀是cockpit）不然会找不到对应的文件

2、我对接的大华的摄像头是H265格式的只能在canvas中展现出来，我这边的功能需要是对视频进行回放和参考链接类似，但是参考链接是能在video中展示因此不需要添加播放、暂停、音量开关、抓图、刷新、全屏功能，canvas中就需要手动添加
